Restating.  Don't you love the person who plays the master of the obvious
role.  I started writing the email and was at the same time looking for
examples of kernel code from 2.4 which we had found that was speculating
addresses and was going to hopefully point out how difficult it was
for us to track down.  Unfortunately, I never found the bugs in our
internal bug tracking system.  I am not sure we ever actually found
the source of the corruption, only that it was occuring.
